Of course, I’m taking about Scooter Libby’s trial, which gets underway today in downtown Washington.Dick Cheney’s former chief of staff is being hauled into the courtroom — 14 months after being charged by Special Counsel Patrick Fitzgerald with lying to the grand jury about his role in leaking the identity of undercover CIA agent Valerie Plame.

It’s good to see somebody finally held responsible for destroying Plame’s career and putting lives at risk — all because Ambassador Joe Wilson, her husband, exposed President Bush’s lies about the war in Iraq. But any joy at seeing Scooter Libby on trial is offset by who’s not on trial.

What about Dick Cheney, Libby’s boss, who sicced him on Plame? What about Karl Rove, who also blabbed to reporters about CIA agent Plame? And what about George W. Bush himself, who put out the word it was OK to hunt down and destroy any critics of his war?

Yes, it’s good to see Scooter Libby finally on trial. But justice will never be done in this case — until all of his co-conspirators are on trial, too.
